GEORGE JACKSON, OF' NEW HAVEN,` CONNECTICUT.

BUILDING CONSTRUCTION.

Application filed September 12, 1919. Serial No. 323,283.

To @ZZ whomy t may concern Be it known that I, GEORGE JACKSON', a citizen of the United States, residing at New Haven, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Building Construction, of which the following is a specification.

This invention relates to an improved col umn for building construction.

A further object of the invention is to provide in a building construction, standard parts such as columns, which `are construct-I ed of pressed steel, punched' and bent at a factory, and which are comparatively light in weight, consequently easily transported, and which can be erected with relative ease, resulting in the saving of expensive labor, such as the riveting and erecting of the improved type of steel I beams or columns now commonly employed for this purpose; and also to provide means whereby the column sections may be quickly and easily connected and enclosed'in `casing blocks of suitable fire-proof material; the said fire-proofing blocks coactin4 with the columns, for providing forms into which cementitio-us material such as concrete, or the like, is poured and allowed to harden to complete the frame work of the building construction,

thereby eliminating therelatively expensive lumber parts commonly used, and the resulting waste of material. t

Other objects of the invention will appear in the following detailed description taken in connection with the accompanying dra-wings, forming a part of this specification, and in which drawings:

Figure 1 is a fragmentary view partly4 in section through a building constructed in accordance with this invention. p

Figure 2 is a cross-section taken on the line 5-5 of Figure l through one of the column 'foundations of the building construct-ion. i

Figure 3 is a cross section through a column of the building construction.

Figure l is a detail perspective of fa retaining plate employed in the building construction. t

Figure 5 is a fragmentary perspective of one of the column structures.

Figure 6 is a detail perspective of a coupler employed in the column structure.

Figure 7 is a perspective view of a stamped plate or sheet, rof which the column is formed, prior to the bending thereof.

Figure 8 is a top plan of one of the standard sections of the column.

Figure 9 is a perspective view of a brace member used in the column structure.

Referring more particularly to the drawings, wherein like characters indicate like and corresponding parts throughout the several views, the columns 20 of the build-y ing construction are formed of a plurality `of the column sections 21 which are formed of sheet steel pressed so as to provide a relatively light structurey embodying sufficient strength and rigidity toproperly re-inforce' the concrete construction of the building and still provide a device which may be easily transported, and lalso easily erected. These column sections 21 are formed of `flat sheets'of metal as indicated in Figure `7 of the drawings, andwhen ina flat state `are punched to provide the spaced* cut-out portions 22 which decrease the weight 'of the columns, and the laterally extending earsl 23, which facilitate the attachment of one Vsection to the adjacent section in a column structure. These ears 23 are splitlongitudinally or laterally of the length of the column section 21, and the portion 24 intermediate thev splits are bent outwardly and inwardly alternately asshown in Figure 5 of the drawings, to provide straps for receiving therebeneath the substantially U- shaped coupling members 25, employed for connecting the various column sections 21 at spaced intervals, in rigidly connected upright position `prior to the placing of the fire-proof enclosing blocks or bricks. Upstanding ears 27 are formed upon the upper end ofthe column sections 21 and they are bent to extend inwardly and horizontally, being provided with perforations 28. In one of the column sections 21, the column rod29 extends through the opening y28 in the horizontal portion thereof, and

where a` pluralityof the column sections 21 are placed in superposed position, as shown in Figure 1 of the drawings, the column rod 29 extends through the opening 28 in the eari27 of corresponding super- 105 posed sections, for connecting andv bracing these sections. The lower end of the column bracing rod 29 rest in a pipe 30, the lower end of which is threaded into a foot or baseI plate 32, preferably circular in plan. This base plate 32 and pipe 30 are embedded in a. foundation block 31. The foundation block 31 is composed of a plurality of blocks 33 of any approved fire-proofing material,v which are connected at their ends by means of the connecting or coupling pins 34, and intermediate their ends by the brace rods or stays 35, the ends of which are anchored in suitable recesses 36, formed in the block 33 and illustrated in Figure 1 of the drawings. `ln case it is necessary to splice the column rod 29, a Ajoint or 'coupling 37,'shown in Figure 6 of the drawings is employed to connect the meeting lends of two sections of the rod 29. This coupling 37 is formed of vfiat sheets of bar metal andhas its ends bent at right 'angles thereto, it also has a `plurality ofrears 38 Vcut therefrom, and bent at rightfangles to the main body'of the joint 'or couplingA plate 37, and parallel to the'iangledrends 39 thereof. The angled ends-39 and the upper and lowermost ears 38 are provided lwith openings 40 which receive' the rod sections therethrough, while the ends of the upper and lower rod sections engage Ythe intermediate 'ear 38. Thus the coupling member 37 will Yconnect the rods and maintain them in theirconnected vertical position 'until the `cementitious ma'- terial is poured into the column, Vand hardened.

The horizontallybent ears 27' of the side column sections 21 are provided or utilized to facilitate the connectingk of Across or lfloor beams, tothe-column structure 20, and spurred pins 41 are inserted through the openings 28 in these angled ears 27 and to engagethe -girder sections 43.V The V,sections 21 are substantially U-shaped in cross section as illustrated in' Figures 3 and 8 of the drawings, and they have 'the corners at the junction oftheir bight portions and legs bent voutwardly and rolled as shown at 44, to receive therein the rolled ends 45 ofi the bracing -members V46. The bracing members 46 lare substantially V-shaped in plan, and their ends are rolled to snugly lit within ythe rolled cornersof the sections21'or'43,` and the apex ofthe couplings are rolled'as shown at 484 to fit about thevert'ical column rod 29, Orbther'analogous bracingVv rod in Vthe buil-ding con-y nected by means of the U-shaped couplings 25, `in the manner illustrated in Figure 3 of the drawings, to provide the desired shape of column. In case the legs of certain of the column sections 21 do not reach, to permit their direct connection, suitable plates as indicated at 50 may be provided for connecting these end portions, as clearly shown in Figure 3 of the drawings, to form a skeleton frame for the column. Blocks 51 of nre-proof material are then placed about the skeleton column formed by the substantially U-shaped section 21. These various blocks 51 are made, from the specifications of the building construction so as to fit about the outer surface of the column skeleton and certain of the blocks `are provided with substantially circular recesses, as indicated at 52, which receive therein the circular corner portions 44, of the column sections 21. The blocks 51 areconnected b-y suitable connecting means as indicated at 53, and when they are placed about the column they provide a form, into which the cementitious material, such as concrete or the like indicated" at 54, may be poured for forming thecomplete column structure, and thereby eliminating the necessity 'of using wood forms or patterns to form the column structures, as is generally resorted to in present approved Vmethods of concrete building structures.

In bracing the column rod 29 within the skeleton column structure prior to the filling of this column structure with cementitious material, spring braces 55V substantially V- shaped'are employed, and these braceshave their end portions rolled inwardly, as shown at 56, in contradistinction toIv the outward rolling of the ends of the braces 46. The apeXes of these substantially V-shaped braces 55 are rounded as shown at 57, to en age about the column rod 29.V
